Christopher Paul Conway was arrested in connection with the rape and murder of one of his 9-month-old twin daughters.

A U.S. Army combat medic was arrested Wednesday and charged in connection to the rape and murder of one of his 9-month-old twin daughters, authorities said.

Christopher Paul Conway, 22, was charged with aggravated child rape and homicide, while the victim’s twin sister was removed from the family’s home and placed in state custody, The Leaf-Chronicle reported.

“We discovered the child had been sexually assaulted, and a cord had been placed around the child’s neck and the child died from those injuries,” Clarksville, Tenn. police department spokesman Jim Knoll told Nashville’s Fox 17.

Clarksville police responded to a 911 call Tuesday morning, and found someone performing CPR on the girl. She was taken to a nearby hospital and was pronounced dead at around 8 a.m.

Homicide detectives found injuries on the girl consistent with rape. They determined that Conway was responsible, Knoll said, The Leaf-Chronicle reported.

Conway later confessed to both raping and killing his daughter, arrest warrants show, The Leaf-Chronicle reported.

The girl’s twin sister will remain in foster care while the Department of Children’s Services investigates the crime.

Conway was booked into Montgomery County Jail on $100,000 bond for the rape charge.

He was denied bond on the homicide charge. Judge Ray Grimes said he could face the death penalty for the child’s murder.
